What do the key ingredients, horse chestnut and troxerutin, do in a product like this?

Horse chestnut extract is traditionally valued in leg cosmetics because it is associated with toned-looking skin and a lighter feeling in tired legs. Troxerutin is a flavonoid derivative commonly used in gels for areas where microcirculation matters to the skin's appearance. In simple terms, these ingredients are included to help maintain the functional state of superficial vessels and the surrounding skin, especially when legs are exposed to long static loads like office work, retail shifts, or travel. They are widely used in products for the venous and vascular cosmetic category. It's important to view them as part of a topical cosmetic formula designed for external well-being and comfort, not as a treatment for medical conditions.
